Time distribution of surface energy on heterogeneous surfaces by inverse gas chromatography

Surface energy of solid catalysts measured by inverse gas chromatography

“…They have been calculated by means of the PC program mentioned before, which is analogous in that respect to another published elsewhere [13]. The same program calculates as a function of experimental time the value of G ✡ and its distribution function for G ✡ as the random variable and time t as structural parameter, ϕ( G ✡ ; t), together with the corresponding values of γ = (γ L 1 γ L 2 ) 1/2 for the mean surface energy of the adsorbates 1 and the catalysts 2.…”

“…[13] and based on the gaseous concentrations of the adsorbate in regions z and y of the experimental cell (cf. Fig.…”

Kinetic Study of Fig Syrup Fermentation by Genetically Modified Saccharomyces cerevisiae Yeast Strains: A Physicochemical Approach to the Yeast Strain Life Cycle

“…), a sub-technique of inverse gas chromatography (IGC) [33], was employed to derive kinetic parameters related to activation energies and rate constants governing the alcoholic fermentation process. This versatile technique, which has found application in diverse studies, including the diffusion and mass transfer of gases over gas-gas and gas-liquid interfaces, the adsorption, desorption and deposition of air pollutants on solid surfaces, the exchange of air pollutants between atmospheric and aquatic environments, the interaction between aroma compounds and food ingredients and transformations in the surface-catalyzed reactions and evaporation of volatile compounds from water [34][35][36][37][38][39][40][41][42], is particularly suited for the kinetic scrutiny of alcoholic fermentation [43,44].…”
